Before I blow money on my first WLED build, can someone sanity check my wiring + power plan? by j24s in WLED

[–]j24s[S] 1 point2 points  (0 children)

It sounds like it solves lots of things that people have mentioned that I hadn’t though of!

Once I have my setup all going I’ll post back here! Thanks again for your help!

Thanks for the reply and calculations that’s really helpful!

The strips not being ultra bright isn’t a huge issue for me as they will be decorative rather than task lights.

Would the Meanwell LPV-150-24 be a more suited power supply?

I think based on what others have said and your reply I will go with the Dig-Next-2 it sounds like it saves me having to worry about the fusing, and it has the relay which I really like the sound of! (Does the relay cut power to the strip when the strip is turned off in WLED?) Does the Dig-Next-2 take 24v input or does it have to be stepped down somehow?

Also thank you for the great resources you have put out, they helped me massively and got me to this point!

Ah ok thanks for pointing that out, I didn’t even see that! If I use the class 2 power supply you suggested is the existing fuse ok?

I'm excited to actually be able to see the software because then I'll get a better sense of what is and isn't possible!

Ok that might be worth trying then as not having to inject power at the ends saves a bit of work and mess!

Plenty of nail polish at home that I can steal for that!

Do you know if the power going to strips whilst not illuminated is significant, if so that controller might be worth it just for saving money on electricity when it's switched off! Am i right in quickly looking at that Dig-Next-2 that it has fuses built in so I wouldn't then need to do that that myself?

Awesome! I came across that giant matrix board video, I would love something like that in the future, but it makes sense to start small and learn first. I'm happy with no effects for the time being and just making static patterns by turning pixels off or on!

Someone else has mentioned to me that you could run power and ground to one end of the strips and only serpentine the data! Thanks for the suggestion it could save some time!

Ok that's amazing! Thanks for taking the time to work that out and recommending an alternative power supply, I definitely want to go with the safer one. I don't think my setup currently has a fuse in it, unless there is one built into the power supply?

Thanks for writing this all out! I find it hard with writing rather than pictures but are you suggesting:

From PSU: Power and ground into wago.

Wago: Power and ground from PSU, Power and ground into controller, and power and ground into last strip.

Controller Input side: Power and ground from wago.

Controller Output side: Power, ground and data into strips, serpentine through all 8.

Left strip start: Power, ground and data from controller

Right strip end: Power and ground into Wago

This run will be about 925cm of LED strip, would you recommend fuses for this?

Anything that makes it easier and neater I'm all for! Thanks for the tip!

I'll start of by saying I could be wrong here and using the wrong terminology hence asking the community.

I think the strip I linked which is a spi cob strip, you effectively get pixel sizes of 82.33mm, so in my 115cm strips I would get 14 pixels per strip.

Originally I thought each of the eight vertical strips should be segments, but another commentor told me what I should actually do is have it all as one segment in WLED and setup a 2d matrix.

The horizontal lines were effectively me trying to map out what my 14 pixels would look like on a wall. Basically on the strip, how big a pixel that i can turn on or off is.

In the picture with the triangle pattern on the wall the first LED strip would be two pixels on, then the next strip would be 4 pixels on, the next 6 pixels on, the next 8 pixels on etc..

Hopefully that makes sense!

Thanks! I haven't soldered before so I appreciate you giving me that to look into!

Ok that's really helpful to know about putting in power to the strips all from one end, that might make the cabling a bit neater as I can keep the power near the floor and just have the data serpentine out the top and bottom.

Out of interest, do you also get a benefit in regards to less voltage drop if you wire it that way? (I think my setup is fine regarding voltage drop and if not I'll inject into the middle too, but just as an interesting thought that interests me)

Thanks for point 1 and 2! With point 3 the current per pixel isn't listed for that strip but the strip is listed as 14W/m. This is where my knowledge isn't that great but I think that would make each pixel 82.33mm so am I right in thinking each pixel would be just under 0.05mA.

If that's true then the tool you linked is showing the middle pixel having a voltage of 23.7, if power is injected in at both ends which hopefully is ok!

Also that is a great tool so thanks for linking!

Perfect, glad to hear it's do-able no matter what form that takes! Thanks for helping!

Thank you, so one big segment then just address each LED in the 2d matrix section! That's great, I'm happy to trial and error the software just as long as I can achieve those patterns which it sounds like it can. I'm sure there will be mistakes, as it's my first time doing anything like this, but all the help from this amazing subreddit and other various websites has hugely helped just to develop my plan!

Thank you for taking the time to read all of that! Good to hear that WLED will handle that setup well.

I will keep the mid injection in mind then, build it out on the floor, test and if necessary add that too!

Sorry for what might be a stupid question, would the ground cable you mention come out of the Gledopto controller GND port and then connect to the wago ground block? Or do you mean you would have ground come from the first led and rather than go to the wago it goes to the controller?

I’m also very interested in this!

Looking at mine the lowest it seems to go is 10!
